External short circuit (ESC) faults pose severe safety risks to lithium-ion battery applications. The ESC process presents electric thermal coupling characteristics and becomes more complex when the batteries operate in large group, which often lead to serious consequences.
Internal short-circuit (ISC) fault in battery systems is considered one of the most severe problems that can result in thermal runaway and fire [4, 5]. Therefore, studying detection methods of ISC and external short-circuit faults of batteries is very important to ensure safety in the lives of people and to avoid major accidents.
This study investigated the internal short circuit (ISC) fault diagnosis method for Li-ion (LiFePO4) batteries in energy storage devices. A short-circuit fault diagnosis method for battery module components based on voltage cosine similarity is proposed based on the characteristics extracted from the ISC fault battery.
To test if a large SOC inconsistency existed in the battery module, the proposed ISC fault-diagnosis method based on voltage cosine similarity was investigated if it could still respond to a simulated ISC fault without a false alarm due to inconsistency.
Single-layer internal shorting in a multilayer battery is widely considered among the “worst-case” failure scenarios leading to thermal runaway and fires. We report a highly reproducible
